pkg-config Readline Not Found #41

Closed Ryushin closed 3 years ago

Ryushin commented 3 years ago

I'm running Devuan Beowulf (Debian Buster) and I downloaded the master branch. When running configure I see:

configure: error: libreadline is required

Running:

pkg-config --cflags "readline"
Package readline was not found in the pkg-config search path.
Perhaps you should add the directory containing `readline.pc'
to the PKG_CONFIG_PATH environment variable
No package 'readline' found

I have libreadline-dev installed. This is probably the same problem as #39 It looks like flags definition is not provided in Debian https://www.marache.net/post/readline-pc.html

I downloaded the Debian libreadline pkg source, compiled it and copied cp ./build/readline.pc /usr/share/pkgconfig/readline.pc Master branch now compiles fine.

Not sure if you want to add a different check or not for readline.

What I would like is for debian to update their readline package to include the .pc file properly :)

Ryushin commented 3 years ago

Looks like Debian has fixed it in the next version: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=901650

Just in case anyone else ends up here from Google like I did...

Rocky 8.5 (and presumably CentOS/RHEL) does not include readline.pc in their readline-devel (or any other) package:

Fortunately this is relatively simple to remedy, create /usr/lib64/pkgconfig/readline.pc:

Excellent job! For ubuntu users the path is ‘/usr/lib/pkgconfig/readline.pc’

How do I add the pc file in macOS? I can't access the folder even with sudo
